The EDS Temperature / Humidity Sensor, OW-ENV-TH, offers an innovative way to easily monitor and control temperature and humidity in indoor environments. The wall mount sensor features both a high accuracy humidity sensor and temperature sensor; as well as an LED, conditional search support, and a pass-through 1-Wire connection. Together these features offer an efficient and flexible system for monitoring the temperature and humidity levels at one or more locations within a building.
The sensor was specifically designed for easy communications. Any general purpose 1-Wire host adapter* should be capable of reading data from the sensor.
The conditional search support allows the 1-Wire host adapter to quickly identify the alarm status for numerous parameters; and the LED and optional latching relay can be configured to behave in a variety of ways, including:
-
Activate when an alarm parameter is met and deactivate when the alarm byte is cleared
-
Activate when an alarm parameter is met and deactivate when readings return to normal range
-
Controlled independent of alarm status.
The LED and optional relay response times are extremely fast; the sensors are able to respond appropriately (activate fan/alarm siren/etc) even before the monitoring application is aware an alarm has been triggered. Since, the EDS Temperature / Humidity Sensor's alarm functions can operate independently of the 1-Wire host adapter the sensor can be used as a standalone Thermostat or Humidistat.
